查询词典 subtraction

The way to find an unknown addend from one addend and the sum is called subtraction. This is the essence of subtraction.

归纳减法的意义：已知两个加数的和与其中的一个加数，求另一个加数的运算，叫做减法。

We cannot always have associative law for operations, for instance, we did not have this law for mixed addition and multiplication,neither for subtraction, 2+3 2+1≠(2+3)(2+1)=5 3,（2-3）- 2≠2-（3-2）,this is why we have to set the rule in operations that "doing inside bracket at first and out side afterwards, doing multiplication and dividing first and addition and subtraction afterwards".

注意运算的结合律并不是永远对的，比如加法和乘法的混合运算就没有结合律，减法也没有，2+3 2+1≠5 3，（2-3）- 2≠2-（3-2），因此我们运算中总是规定先括号内再括号外，先加减后乘除。

Thus, every member of UIO education is willing to dedicate oneself into our business.Our account bill carry on the principle of "addition, subtraction, multiplication and division". Addition means that we must provide the value added service to our customers, and exceed the customer's expectation; Subtraction means that we must refuse the waste inside the company; Multiplication means that we must insist to have a strong teamwork, share with everyone to gain the mutually promotion; Division means that we must refuse any illegal, wrongful or dishonest cooperation.

我们企业的账目清单执行"加减乘除"发展--"加法"：始终坚持为客户提供更多的增值服务，超越客户的期望；"减法"：始终坚持拒绝企业的内耗、最大程度的减少客户的损坏；"乘法"：始终坚持成员之间的紧密协作，优势分享，相互促进，实现企业与合作伙伴的资源共享、联盟合作；"除法"：始终坚持废除无意义的浪费，排除一切非法的、不正当的、不诚信交易与合作。

Results: Before intervention, the total scores, A (antisocial/disobey behavior) and N scores of the Ratter Parent Scale were of no difference. After intervention, the total subtraction scores (4.10±3.21), A subtraction scores (1.10±1.37) and N subtraction scores (1.32±0.91) in the intervention group improved significantly (P.05 -0.001), the recovery rate by clinical evaluation was 34%.

结果：干预后，比较两组Rutter儿童行为父母问卷的减分值，干预组总分减分(4.10±3.21)、A分减分(1.10±1.37)和N分减分(l.32±0.91)与对照组总分减分(l29±3.15)、A分减分(0.53±117)和N分减分(071±110)相比差异有统计学意义（均为P.05），干预组有34%的儿童恢复正常。

The arithmetic of the subtraction is based on the serial arithmetic. It can entirely enumerate every pair of subtrahend on a bit, and it also calculates two possible loaning carry values on each bit. So the subtraction can be operated through automatic selection, and complete collateral subtraction and carry operation. The method of single division is same to it. With the stenography of shifengshou we can solve the complex division. We put the formula and the technique into the DNA model to get the result. The methods all make the step decrease and change the conventional arithmetic.

减法的DNA 算法理论主要是来源于串行思路中的算法，它是将每一位上的两个减数对的所有可能进行全列举，同时考虑每一位上的两种借位信息，使得运算进行自动选择，一步即可得到最终结果的算法；除法中一位数除多位数的算法还是从我们平时所进行的串行运算中得到启发而设计的算法；而除法的多位计算思路则来源于史丰收速算法，将算法中的口诀及技巧应用到DNA 链当中，使得传统中的代数运算能够并行的得到最终的结果，这三种算法的设计都使得计算步骤减少，从根本上改变了算法的运算机制。

Our within-subject analysis also showed activation of brain areas associated with negative emotions, including right insula and putamen (11, 38), during the high-stress relative to the low-stress task. The observed activation in the dorsomedial prefrontal cortex ACC and precuneus parietal cortex may ref lect mental arithmetical performance (39) and assessment of the mental state (40) during the serial-subtraction task, whereas the CBF reduction in pre- and postcentral gyri and temporal cortex may ref lect more frequent verbal movement and greater auditory stimulation during counting backward versus serial subtraction.

我们的在之内主题分析也显示了脑子区域的活化作用与消极情感相关，包括正确的脑岛并且putamen (11， 38)，在期间高注重相对低注重任务在连续减法任务期间，被观察的活化作用在dorsomedial前头叶外皮ACC和precuneus头顶骨外皮可以ref lect精神算术对精神状态(40)的表现(39)和评估，而CBF减少前和中央后回和世俗外皮可以ref lect更加频繁的口头运动和更加伟大的听觉刺激在计数期间落后对连续减法。

Objective to evaluate the clinical value of dr energy subtraction in chest acute trauma.methods collected sample data based on 122 clinic cases of diagnosed rib fracture patients in chest acute trauma,75 male,47 female,age between 12~65 years old,with an average 36 years old,using dr energy subtraction technique to exam and 45 cases were examined by ct in chest.results in all the cases,the diagnostic rate of single rib fracture,multiple rib fracture,rib fracture with hydropneumothorax,rib fracture with pulmonary contusion was 86.7%,91.3%,90.5% and 94.1%,97.1% in multiple rib fracture of energy subtraction image.conclusion dr energy subtraction technique which can show rib fracture and lung complication clearly has important diagnostic value for the patients with chest acute trauma.

收集122例临床诊断肋骨骨折的胸部急性创伤患者，男75例，女47例，年龄12~65岁，平均36岁，进行dr能量减影胸部摄影检查；其中有45例患者同时作ct检查。结果在本组病例中，标准胸片发现肋骨单发骨折、肋骨多发骨折、骨折合并液气胸、骨折合并肺挫伤的检出率分别为86.7%、91.3%、90.5%和94.1%；而能量减影仅在肋骨多发骨折中检出率为97.1%，其余检出率均为100%。结论 dr能量减影技术可清晰显示肋骨骨折和肺部并发损伤，对胸部急性创伤有重要诊断价值。

Conventional imaging technique which unsubtracted bone was used first,use 3D treatment on workstation to reconstruct cerebral vessels,to diagnose aneurysm,vascular malformation and tumor as well as to evaluate the preoperative and postoperative efficacy.Subtract bone techniques including one by one slice subtraction,semi-automatic digital subtraction radiography,matched mask bone elimination and control tube exposure light spot imaging technique can show the vessels more clear without the interference of bone as well as the relationship between vessel and pathological changes more accuracy.

首先是未去骨的常规成像技术，利用工作站进行多平面重建技术、最大密度投影、容积再现、表面遮盖法等多种三维处理得到头部血管及肿瘤图像，对动脉瘤、血管畸形及肿瘤血管进行病变诊断及术前、术后评价；其次是近年出现的逐层减影、半自动数字减影、匹配蒙片骨去除法及控制球管曝光点的减影等去除颅骨的减影技术，没有颅骨的干扰血管显示更加清楚，血管与病变关系显示更准确。
